PORTABLE DISPENSING DEVICE.

Application filed April 12, 1922. Serial No. 551,812.

To all 'ZIU/IOIII, it may concern:

lie it known that 1, CHARLES SrAn'rn, a

citizen of the United States, residing at Cleveland, in 'the county ofCuyahoga and State of Ohio, have invented certain new and usefulImprovements in a. Portable Dis pensing Device, of which the followingis a specification.

This invention relates to dispensing de- .vices for lubricating oils,and has for an object to provide a portable container with a pumpadapted to deliver accurately measured quantities of oil, a furtherobject is to provide means for holding said container against movementduring operation of the pump. A further object isto enclose the pistonrod. in a closed housinp to eliminate oil leakage. Other objects will beapparent from the following description in connection with the annexeddrawings.

In said annexed drawings:

Fig. 1 is a side elevation showing the devicein use for filling an.automobile transmission case.

Fig. 2 is a top plan view of the device.

Fig. 3 is a broken vertical section showing the container in section anda portion of the pump in side elevation and a portion thereof insection.

Fig. 4 is a broken vertical section taken at right angles to the sectionshown in Fig. 3.

Fig. 5 is a section on line 5-5 of Fig. 3.

Fig. 6 is a perspective view of a modification. 7

\ Referring to the drawing-a cylindrical sheet metal container 1 isprovided with top 2 having, a filling opening 3 therein closed by adetach able cover l and an opening 5 at one side of the opening 3 inwhich fits a vortically disposed pump cylinder 6 supported on a flange 7engaging' the top of the container about the opening 5 and boltedthereto.

The cylinder 6 has a closure plug 8 in the bottom thereof which has acountorbore S) on the under side thereof tapped to receive the upper endof an intake conduit 10 which extendsdownwardlv to adjacent the bottomof the receptacle, and perforations 11 through which the conduit 11)communicates with the interior of the receptacle.

A check valve 12 normally seated by gravityupon the upper side oi theplug" 1) prevents escape of oil through the perforations v1.1 on thedown stroke of the plunger. A

piston 13 is movable vertically within the cylinder 6 and has a pistonrod 14 fixed:

thereto and extending upwardly and openlugs 15 therein to permit oiltoflow therethrongh'on the down stroke, thereof. A. check valve 16 isslidably mounted on the rod 15 above the piston 13 and is normally ,7held seated upon the piston over, the openingrs 15 by a coil spring 17.An outlet conduit 18 communicates with the upper end of the pumpcylinder 6 above the top of the receptacle 1. The cylindrical piston rod14 has rack teeth 19 formed between parallel transverse notches in onesideof the rod. A transverse shaft 20 is journaled in the upper end ofthe cylinder 6 and has a pinion 21 within the cylinder meshing withtheteeth 19 on the piston rod. A'crank 22 is fixed to the outer end ofthe shaft 20. An extension ill housing 23 is secured to the top ofcylinder 6 enclosing the upper end of the piston rod 14. A set screw 24in the upper end of the housing 23 forms an adjustable limit stop forthe piston 13. An angle foot plate 2.5

I is secured to the wall of the container at the bottom thereof by meansof which the operator can hold the container against movement duringoperation of the pump.

In operation the crank 22 is turnedto raisethe piston 13 until the rod14 engages the set screw 24. During the upward movement of the piston 13oil is drawn through the inlet conduit 10 past the check valve 12 intothe cylinder 6 filling the portion of the cylinder beneath the piston13. By properly set-ting the stop member 24-the exact amount of oildesired can be drawn into the cylinder 6. Thecrank 22 is then rotated ina reverse direction until the piston 13 is seated upon the bottom of thecylinder 6. During the downward movement of the pump, the check i alve16 is forced upwardly against the actioh of the spring 17 and the oillows throhgh the openings 15 in the piston 13. raise the piston 13 untilthe rod 14.- again strikes the limit stop 24. During upward movement ofthe piston 13 the valve 16 is held sealed by the pressure of the oil andthe oil above the piston 13 is discharged from the cylinder (5 throughthe discharge conduit 18. By housing the piston rod 1 1 in an extens nof the pump cylinder it is not necessary to provide a packed tight fitThe crank 22 is then rotated to oo of the cylinder and leakage of oil iselimiquantities less than a full hated. The pinion 21 and rack teeth 19are preferably so proportioned that for each 7 revolution of the crank22a certain unit volume of oil is discharged so that measured cylinder'charge may be delivered through the outlet conduit 18 y turning thecrank 22 through the desired number of revolutions.

" The container is made of relatively thin sheet metal, including thetop 3, and a metal stifi'ening bar 26 is fastened diametrically acrossthe bottom face of this top intermediate openings 3 and 5 where one ofthe fastening bolts 27 ,for the pump may pass through the bar, and unitethe parts together. Thus bar 26 sustains the Weight of the pump, thestrains in action, and permits the entire container when loaded to becarried bodily by gripping column 23 Without danger of buckling ordamaging the thin-top 2 of the container. In Fig. 6, a skeleton frame.28 is provided for container 1 comprising a base ring 29 upon which thefoot may rest to hold the container stationary when turning the crank.

of the operator What I ciaim,.;s:

1. A dispensing device for oils and greases, comprising a sheet metalcontainer having a pump body extending downwardly through its top, lugsextending from the mated upon said top, a cylindrical extension tor saidbody exposed above said top, operating means within said body having acrank outside said container, and a rigid bar extending across said topwithin said container support for said pump, and means uniting one ofsaid lugs and bar and top rigidly together.

2. A dispensing device, comprising a portable receptacle having a sheetmetal top, a pump cylinder suspended from the top of said containerhaving liftpump mechanism therein, a crank at one side of said containerproviding a supplemental adapted'to operate said pump mechanism, a I

re-enforcing member for said sheet metal top, and fastening means forsaid pump cylinder connected with said re-enforcing member. In testimonywhereof I afii r my signature to this specification.
